The Assessment of Sensory Interaction in Single Leg Stance: A Pilot Study

Abstract

A clinical method for the assessment of sensory co-ordination in balance was first described by Shumway-Cook and Horak (1986). This test was based on the principles developed by Nashner (1983) in his dynamic posturography studies. Nashner and his co-workers used a force platform and a visual surround, either or both of which could be sway-referenced to give reduced or conflicting somatosensory and/or visual information. By systematically varying the visual and somatosensory information available for balance, Nashner was able to examine the individual's ability to use this information or to ignore conflicting sensory input.
